Instantly lower temp
Works great. My car was normal operating temperature 200 F and after I installed the thermostat now getting 185 F. Replace your thermostat and at least the rotor on your water pump if your car occasionally overheats. Good quality. Like oem quality.

Super reliable item
Replacing this thermostat housing (which has a thermostat inside), along with a new AISIN water pump, solved my overheating problem in my Prius V. This is an AISIN brand which--to let folks in on a possible secret--is the same item sold by a Toyota dealer parts department. They just grind off any Toyota branding information. Hence, this is a very reliable product. It's great to not have to worry about overheating my Prius V when I drive it. Had I not monitored the temperature before I installed this thermostat, I could have toasted my engine. I am very pleased with this product.

Fit 2016 Toyta Prius. (Actually a 2012 Prius with the 4th gen swap)
It fit, and it works. Never would’ve thought that a thermostat could affect gas mileage so much.

Works on my 2010 Gen3 Prius
Seems my last thermostat was open for 4+ years. Seems to open around 180F with a max temp of 188F so far. Was slightly different than the one I took off, but worked fine.My old gasket stuck to the engine and I had to peel it off and then scrape clean with a razor blade. I did not know that I was going to lose about a gallon of coolant. I needed to buy more.

Poor packaging
Part worked good!4 stars due to shipping. Sold by Amazon but it shipped in its original packaging so it was half open and sliding around everywhere.

great thermostat
no issues using this thermostat. It was hard to install, but that is not the thermostat's fault. I decided to clean the manifold, pcv value and throttle body, so after taking that stuff out, it was easy to install. I bought this because i was already going to change the water pump on my daughter's 2010 prius.
